The development and optimization of a fluorometric reaction
rate method for the determination of aluminum is described.
Modifications to existing instrumentation permit automatic
monitoring and reporting of measurement conditions. Automatic
correction of measured analytical signals is provided if monitored
parameters deviate from optimum values. A computer controlled
standard addition procedure...
A facile route to bicyclo(2.1.1)hexanes was developed involving
the intramolecular photocyclization of 1, 5-hexadien-3-one to
bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride
reduction demonstrated the strain present in the ketone.
Further evidence was obtained from the failure to introduce substituents
alpha to the...
A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
The purpose of this investigation was to determine the nature of the
chemical constituents of incense cedar bark with the hope that such an endeavor
would spur future research, development and use of a now neglected
natural raw material.
The bark from nine trees, which were separated into three age...
A simultaneous direct spectrophotometric method for the determination
of barium and strontium using Sulfonazo III has been developed
making use of the chelons EGTA and CDTA at controlled pH
values.
An absorbance study of the barium and strontium complexes of
Sulfonazo III revealed that there is no pH sensitivity of...
